Measurements of the $\mathrm{D}(t, \alpha )n$ reaction cross section at triton energies of 1.9 and 1.5 Mev have been made to resolve a disagreement among previously published values. Corrections for published values of the ${\mathrm{He}}^4(t, t){\mathrm{He}}^4$ and $\mathrm{T}(t, t)\mathrm{T}$ scattering cross sections are also suggested.
